Abstract

Cardiotensor is an open-source Python package designed to quantify 3D cardiomyocyte orientation in whole- or partial-heart imaging datasets. It provides scalable implementations of structure tensor analysis and tractography for teravoxel-scale datasets, enabling extraction of directional metrics such as helical angle (HA), intrusion angle (IA), and fractional anisotropy (FA).
